Miniature trap, take advantage of bad opening play

nice, an english opening versus the carokahn i think.... whether this was artificially made by calculations or real game, nice trap, kills the queen early. keep up the good work

 it is a weird variation of the Queen Pawn opening deferred - French Variation.

While this may not happen that often (maybe 1 game every year!)  it is still pleasing.

I found 21games on Game Explorer that goes until 4.Nec2. But in none the black response was 4...d3, I think because 5.Nf4 wins the pawn on d3 (attacked from the N and the B).

So the big white mistake on this oppening may be 5.Nc3.

oh yeah, 3. c4xd5 would be better? anyway, nice trap, thanks "Shuttlechess bad player" to show the possibility...
